how much Clorox do I add before filling the tank prior to not being used for
a long time? I have already filled and drained
4 times but now want to sanitize for any bacteria. I think it is 1/4 cup,
leave set and slosh around while on the road for the first day and then
redrain, refill and
redrain one more time the first day out.
Does this sound right?
Thanks

Hi Ray
Do you have your GMC Operators Manual? In the 1976 Operators Manual on page 100 it says:
Sanitizing Living Area Water System
To help assure complete sanitization of your living area water system, it is recommended that the following procedures be followed on a new system, one that has not been used for a period of time, or one that may have become contaminated:
1. Prepare a chloride solution using one gallon of water and 1/4 cup of household bleach (5% sodium hypochlorite solution). Pour one gallon of solution into water tank for each 15 gallons of tank capacity.
2. Complete filling of water tank with fresh water. Open each faucet and drain cock until all air has been released from pipes and entire system is filled.
3. Allow to stand for three hours.
4.Drain and flush with potable (drinkable) fresh water.
5. To remove any excessive chlorine taste or odor which might remain, prepare a solution with one quart of vinegar to five gallons of water and allow this solution to agitate in tank for several days by vehicle motion.
6. Drain tank and again flush with potable water.
I have found that one can just pour 1/2 cup of bleach into the tank fill spout and then fill with water. Filling will mix it well enough. Then open your faucets, etc. until you have flow through them. Do steps 3 and 4.
I skip step 5 and just fill and drain my tank a couple of times and most of the chlorine odor will be gone.
You don't have to drive it. Just do it while it is sitting in its parking spot.
I do this prior to every trip.

Use the Hydrogen Peroxide mix. Chlorine bleach is tough on components that may or may not be wetted by the water in your tank.
If you use bleach, rinse twice and do not let it set in the tank for a long time. 3 hours sound about right. Hydrogen Peroxide is less corrosive or reactive with other components of your house water system. Rincing is still called for.

Sounds like too much for your size tank. I misread directions and instead
of a capful
per 10 gals I put in a cupful. This went into a 400 gallon water tank on
my boat. I realized
my error when I opened the ice maker door. The aroma almost knocked me
over but the ice
was a pretty green.
